C# | Get the number of nodes contained in LinkedList<T>

LinkedList<T>.Count property is used to get the number of nodes actually contained in the LinkedList<T>.

Syntax:

public int Count { get; }

Return Value: The number of nodes actually contained in the LinkedList.

Note: Retrieving the value of this property is an O(1) operation.

Below given are some examples to understand the implementation in a better way:

Example 1:

// C# code to get the number
// of nodes actually contained
// in the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a LinkedList of Strings
        LinkedList<String> myList = new LinkedList<String>();

        // Adding nodes in LinkedList
        myList.AddLast("Geeks");
        myList.AddLast("for");
        myList.AddLast("Data Structures");
        myList.AddLast("Noida");

        // To get the number of nodes actually
        // contained in the LinkedList
        if (myList.Count > 0)
            Console.WriteLine(myList.Count);
        else
            Console.WriteLine("LinkedList is empty");
    }
}

Output:

4

Example 2 :

// C# code to get the number
// of nodes actually contained
// in the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {
        // Creating a LinkedList of Integers
        LinkedList<int> myList = new LinkedList<int>();

        // To get the number of nodes actually
        // contained in the LinkedList
        if (myList.Count > 0)
            Console.WriteLine(myList.Count);
        else
            Console.WriteLine("LinkedList is empty");
    }
}

Output :

LinkedList is empty
